About this sunscreen
B&B DERMA Sun-day Milky Mineral Sunscreen SPF 50+ is a pure mineral formula using Titanium Dioxide and Zinc Oxide for broad-spectrum defense. It dries down to a matte finish and is gentle, with a no-sting profile and low pore-clogging risk that suits sensitive skin. As a mineral product it can leave a medium white cast and feels a touch heavier on skin, which is common for zinc-based formulas. With a good protection rating and a score around 80, it is a solid mattifying mineral option.
